Power Electronics Technician

Power Electronics Technician

Main Mission

Ensure the design, assembly, testing, commissioning and maintenance of power converters and high current/high voltage electrical power systems on site.

Activities and Responsibilities

• Maintenance & Troubleshooting: Diagnose and repair faults on power converters (from a few kilowatts to several megawatts) powering superconducting magnets or radiofrequency cavities.

• Testing & Validation: Perform electrical tests on test benches and in situ (performance measurements, thermal, high precision current regulation).

• Integration & Wiring: Assemble power electronic sub-assemblies (power racks, busbars, IGBT/MOSFET modules, cut-outs).

• Control & Interfacing: Connect the power section to control-command systems (acquisition cards, FPGA, communication buses).

• Documentation: Write test procedures, intervention reports and keep electrical diagrams up to date.

  
  

Profile & Key Skills

• Technical: Static converters (choppers, inverters, rectifiers), power components (IGBT, diodes, SiC), electrical safety and high voltage authorisations.

• Tools: High voltage oscilloscopes, network analysers, load banks, precision multimeters.

• Soft Skills: Absolute rigour (strict compliance with safety standards in experimental areas), team spirit and responsiveness during technical shutdowns
